In the practice room, I’m smart, organized, and focused. I’d like to say that this always leads to performances that are relaxed, poised, and confident. But sometimes the smart guy from the practice room fails to show up, and instead a much dumber version of me ends up on the stage: nervous, distracted, and scatterbrained.

It’s my job (the smart guy) to make sure the dumb guy is prepped and ready to go. He’s not much good at thinking on his feet or making good musical decisions, but he’s trainable. So here’s the preparation regimen:

Practice in a thorough, methodical way. Not just the hard parts—the easy parts, too, which the dumb guy thinks he can handle but will be prone to boneheaded mistakes.

If recordings of the repertoire are available, listen to them over and over. Sometimes when the dumb guy’s reading or memory fail him, his ear can help him through.

Include a clear breathing plan in the practice routine. Mark the breaths in, early in the process, and practice them like they are notes. My particular dumb guy tends to breathe in weird places when he gets nervous, so I have to make sure good breaths are part of his muscle memory. (If you have a dumb guy/girl, they might have their own personal quirks that need a safety net.)

Make extensive markings. Anything that the dumb guy might forget gets penciled in, in clear and unambiguous terms (no just circling things—the dumb guy can’t always remember in the heat of the moment what the circles mean). If necessary, I even leave him a little reminder a few bars in advance (“big breath coming up,” “keep fingers relaxed,” etc.).

Make foolproof arrangements for page turns. Sometimes that means things like making a couple of copies of a page, with some bars completely blacked out so the dumb guy can’t accidentally play past the page turn, or fail to find his place after turning. Sometimes I even leave some instructions in the margin about how to do the page turn successfully.

After the recital or concert, I review the dumb guy’s performance to figure out what other holes he managed to fall into, and strategize about how to plug those holes for next time.

If you’re like me, and your IQ sometimes drops a few points under the hot stage lights, make sure you’ve done your advance work so the dumb guy can’t cause too much havoc.
